Working with Michał is always very inspiring. Personally, as a supporter of Domain-driven design, I know in every conversation with Michał a deep understanding of the subject. His focus on accurately defining the problem and then achieving the desired effect is a confirmation of the level of an expert. The masterful technical level completes this picture.

Training with Mike is a real feast of knowledge. Mike is a DDD practitioner, and the material presented during the training is filtered through Mike's design experience. The training material was tailored by Mike to our needs based on the survey. During the training, Mike answered and often performed livecoding to answer the participatns' questions. I'm glad we decided to cooperate.

Seasoned consultant, Domain Driven Design expert, test-first development practitioner, founder, and a great educator. Mike is the guy who has it all. He has tons of practical knowledge and a gift for sharing it. A rare combination. I'm very glad that he has recently gone beyond our local community and started an online learning program. It's called ''How To Be a Professional Developer" and I was lucky to be one of the early adopters. As a participant, I'm happy to recommend it to any developer with a few years of industry experience. What makes it unique is that it doesn't have a format of a typical (boring) course. Instead, it's a living community where you can engage with other participants. Join the online consulting sessions, or in-depth discussion, if you'd like to. Or simply go through the materials at your own pace. The choice is yours. Furthermore, you're encouraged to become a co-author and suggest the next topics/your own ideas. The idea of a living course is based on an iterative process. Mike is gathering the feedback, structuring the modules, and releasing small, actionable lessons. Needless to say, the information is always useful & practical. It's all about the quality & hands-on approach. In short: what you get is 100% solid, actionable tips, and no fluff. My professional toolbox has more tools to use now. Especially when it comes to code testing & techniques around it. But there's more yet to come. Think of areas related to DDD, Event Sourcing, etc. Wanna learn from a seasoned practitioner who is a few steps ahead of you? Join the program and check it out yourself.

Michał is a great and competent teacher, and I know him from many previous initiatives. I was not very surprised, when it turned out that his training program is simply great. We received valuable materials with practical tips on Software Craftsmanship techniques (mostly related to TDD for now). In addition to the lectures, we got the opportunity for direct consultations. All this together makes the whole program very valuable, both for experienced programmers and for people starting their adventure with programming. I highly recommend it!

The program showed me a new perspective on TDD and how much I don't really know. Finally, I was able to easily understand the topic of what a unit is in testing. I noticed the value that the proper application of TDD can give me in my daily work. You can count on the help of a mentor and participants if you have any questions. There are a lot of interesting discussions on the private forum to read in your free time.

Stuck in a small company without the opportunity to grow, HowToBePro helped me to grow and answer some difficult questions about software design - this is an invaluable resource of software craftsmanship..

I totally recommend this mentoring program, not only as the best example of teaching I have seen in a long time but also because you come out with a clear set of practical skills which allow you to immediately start using in the project Mike is an incredibly competent and approachable teacher who paces his workshops well and teaches the essential elements of a TDD and architecture. He is very helpful, once per month we could bring a problem and discuss it and how to solve it. As an architect, I see a lot of positive impacts that this mentoring program brings into my IT world.
